SHOCK ABSORBING DEVICE Fil ed Aug. 25, 1927 'IIIA ?III/11111111) Patente d Jan. 20, 19 31 JOSEPH P.`CE1\VTVTEIR OF HARLOWTON, vrovmsnnn and highly efiicient devicewhich may be readily applied in its proper'po'sition and easily removed therefrom if desired. The jscope 'of my invention extends to whatever constructions may be defined'by or included in the terms vor language of the appended clans.

In the drawings zr simple form o-f motor'car embodying my in vention;

Figure 2 is a similar view illustratng the invention as appled to the rear springs;

Figures 3 and 4: are detailed views showing the ends of my improved auxiliary spring in poition with respect to the usual leaf spring Figure 5 is a detailed view illustrating another form of myinvention. p

'My invention' in the form or em'bodiment shown in the drawing comprises a spring, 10, i having oppositely extending portions, 11 and 12, to which are attached attheir extreme ends retaining members indicated generally asat,13. r f i As is clearly illustrated in Figures land 2 of the accompanying drawing the auxiliary spring, l0,-is held in its proper position be low the usual leaf springs, 14' and 15 by means of the clips or bolts, 1 6 and 17. Each end of' the extensions, 11 and 12, asis clearly shown in Figure 3, is provided with circularly bent,

or loop portions, 18, ,for the purpose of supporting the retaining members, 13.` i

These retainingmenbers, 13, are preferably formed with `a'shaik portion, 19, which is aclapted'to fit the loop, 18,a`nd a pair of v of the loops, 18, sufliciently to overlap or eX- tend beyond the' adjacentleaf 'spring of the motor vehicle, for the purpose of preventing Figure 1 is apartal front elevation of a enlarged hubs or fianges, 20. The flanges,

auxiliary'springs with respect to the usual spring members. V u i i i Figures 3 and 4 illnstrate, the 'extreme or' loop ends, 18, of my auxiliary 'spring as bear ing directly against the adjacent leaf of the 15' main spring for the purpose' of minimizing i i the friction therebetweei. g Although the auXiliary spring-is of substantially the same width' as the usual leaf spring it is obvious that the thicknessthereof may be increased according tothe load of the p particularmotor vehicle to which it`is atr tached. i x r i By reason of the fact thatthe points of contact between my auxiliary spring' and '6 the'main leaf springs are located near the eX- treme ends .oftheleaf springs a very eficient cushioning' or Shock absorbing action is ef;

I claim 1- r leaf member bowed upwardly intermediately of its ends 'for contact upwardly with the central portion' of said leaf spring, said p 'spring leaf having its eXtremities bearngup wardly against the leaf spring adjacentits respective ends and the portions thereof be-` itween its upwardly bowed center 'and said extremities spaced beneaththe leaf, spring,-
